In general my device comprises an adjustable frame suitable for slidabymounting over an elongated striping nib unit, and may be mounted di- 2Orectly thereon or by a special guide thimble, the frame carriers mountedthereon, either xedly or adjustably, roller or ball tipped guide arms,and preferably provided with some adjusting means therein forcompensating for irregular surface formations over which the striper isto be applied.

My invention may be best understood when described in combination withthe paint striping unit with which it is to be used.

I will now describe more fully the detailed construction of myadjustable paint striper guide, referring to the drawings and the marksthereon.

The preferred type of guide frame is set forth in the Figs. 3 and 4 ofthe drawings, showing the guide as adapted to the universal type ofstriper unit, although it is equally as adaptable to other types of`striping units such as is illustrated in the Figs. 1 and 2 of thedrawings, and which type is more fully described in my patentapplication Ser. No. 625,741, filed July 29, 1932 as heretofore referredto, this application being a division thereof. I

The universal type of striper as illustrated in the Figs. 3 and 4,comprises an elongated striper 45 nib l having the body formed ofsuccessively stepped cylindrical sections a, b, c, and 11, allconcentric about the same axis, and having a small, pinned surfacestriping disc 2 rotatably mounted in one end thereof, said disc beingpartially inclosed by a curved spring member 3, the body section beingprovided with a central paint channel e lengthwise thereof leading tothe said striping disc. The cylindrical end section a of the nib body isformed with an annular groove recess Y container Vl through the collarwalls and opening into the annular groove 4 of the nib end, providing acontinuous paint passage from the container to the striping disc 2. Acontrol valve 9 formed with a port i9 is slidably mounted through thecollar G, intercepting the paint passage 8, Vfor opening and closingsaid channel as the valve 9 is displaced endwise therethrough,rsaidvalve 9 being formed with an engaging groove II at the d Slidablymounted over theY outer end thereof. nib body sections b, c, and dis ashouldered cylindrical guide thimble I2 formed with an end flange collarI3, said collar I3 positioned to engage the valve end groove II of thecontrol valve 9, for

.moving said valve simultaneously therewith and allowing completerotation thereof about the thimble aXis without disconnecting the valvetherefrom. A compression coil spring I3 is mounted between the guidethimble I2 and the nib body I, engaging their respective shoulderedends, displacing said thimble I2 to a position adjacent the mountingcollar 6, likewise displacing the connected control valve 9 therewithand closing the Y paint passage channel 8 leading to the striper nib I.Mounted over the guide thimble I2, at right angles thereto, is a guideframe I4, preferably slidably mounted thereon and splined thereto,having a clamping screw I5 mounted therethrough and provided with a locknut I6 for rigidly clamping said frame in any desired adjusted positionon the thimble.V When desired, the frame I4 may be xedly mounted on thethimble I2, either by a pressed iit or by any other means which willrigidly retain the frame thereon. An arm .block I 'I is slidably mountedon the under Y side of the frame I4 by means of rigid slide .rods

l8- which are positioned to slide through the frame slide recesses, andare clamped therein at any adjusted position by the head of the screw I5and the nut I6, the adjustment of said arm block Il being always atright-angles to the axis of the nib Vbody l. Guide arms I9 formed ofrigid metal posts are xedly mounted in the armV block I 'Land preferablyprovided with ball tipped ends formed of a contact ball 2D and thesmallrbearng ball ZI mounted therebeneath, although any type of slidingor rolling end contact will operate, and should be selected and adoptedas the guide rib or template with which it is to be operated mayrequire. The purpose of the guide unit is twofold; primarily to engage aguiding rib f or similar template edge, for directing the -line oftravel of the striping device disc 2 along a predetermined path over thesurface to be striped, and, secon- Vdarily, when applied to theuniversal type of Vpositioned slightly back of the striping disc edge,

as indicated in the Fig. 4 of the drawings, the operator holdingthestriper unit in his nger tips by grasping same on opposite edges of theframe I4, and thenV applying suflcient pressure thereto when said disc 2is placed againstthe painted surface y, displacing the striper nib bodyl and 2 ofthe drawings, the guide thimble I2 is 15 omitted and the frameMa. mounted directly over the cylindrical casing end h of the striperbody 22, and clamped'thereon in its adjusted position with therespective guide arms positioned slightly Y ,Y back of the surface gasin the former case. The

nib body Ia. being slidably mounted Within theend casing h and issplined thereto, may be displaced lengthwise therein against theretaining spring 23 by applying pressure to the nib disc 2a asin theformer case heretofore described, the 25 operation being also thesame. Y

The guide frame as shown in Figs. 1 and 271s the same in generalarrangement and principle as that illustrated in the Figs. 3 and 4,although the mechanical details are slightly simplified in design, theframe being provided with an ordinary set screw 24, also with asupplemental guide arm 25 on the top side *thereof which may beY used asarspecial guide member, or removed asV desired. Y e A modiiiedV form ofmy guide is illustrated ln Figs. 5 and 6, showing a solid, butangularlyV shaped guide frame |41), fixedly mounted on a cylindricalguide thimble I2b, either by a pressed iit thereon orv by a set-screw2B, and is provided o Y. Vwith variously positioned ball tipped guidearms I9b iixedly mountedV therein, each set being positioned to engage adifferent type or kind of guiding rib or template edge, and making thestriping device adapted to two operations `on differ- 45 ently ribbedsurfaces or template` guide-edges, and without changing or adjusting theguide frame. The size, shape, type and position of ,any or all of thevarious guide arms maybe varied and changed as required for engaging andoperating with diiferenttypes or styles of rib or template edges,depending upon the condition under which the striping device is used.

Figs. 7 and 8 illustratea furthermodied form of my guide, beingY formedof a solidV-at guide V frame block I4c with a central cylindricalopening for xedly, or adjustably, mounting on the guide thimble I 2candis provided with two types of guide members as anillustration ofapplying diiferent kinds of vguide ,members` onthe Vsame 00 frame, i.e., theball tipped guide arms I 9c and the rotatably mountedguiderollers 2`I,Y the different sets or types being mounted on oppositesides of the frame |40, each beingV designed andV positioned to engage adifferent type or shape 55 rib or template edge, also making thestriping device adaptable to dilerentV striping Ygages and templateswithout adjusting Vthe guide frame Vthe same as in the former case.

The Figs. 9 andlO illustrate a further modi'- 70 cation of the frame orguide unit shown in the Figs. 7 and 8, by mounting the special guide armmembers I9c and 21 on separated arm ,blocks 28 and 29 but in the samemanner as before, and

hingedly attaching same to the guide frame I4d 75 on opposite sidesthereof by hinge pins 30, the trame Idd being xedly, or adjustably,mounted on the thimble 42d as in the former case. The arm blocks 28 and29 when either, or both are closed in the guide frame Md occupy exactlythe same position as in the Fig. 7, and are retained in that position bya double hook spring bar 3l mounted within the side groove lc andretained therein by the pin 32, the hook ends m and n engaging theblocks 28 and 29 respectively retaining them rigidly in the closedpositions, or when disengaged therefrom, either at one or both ends willallow either block 28 or 29 to be opened to a position as shown by thedotted lines in the Fig. 9 of the drawings, removing the guide memberwhen not in use and which might obstruct the movement of the striper ifprojecting objects on the painted surface were positioned in linetherewith. The operation is the same as in the former case.

It is apparent that my device is subject to various modifications inboth design and detail arrangement of the various elements and units ofwhich it is comprised and without departing from the spirit of myinvention, and I claim not only the designs as herein illustrated butal1 modications thereof that is substantially a substitution of parts orunits herein shown.
